Secrets to Perfect S'mores Cookie Bar Success
Perfect Crust: Press the graham cracker crust very firmly into the pan - this prevents crumbly bars that fall apart when cut. Use the bottom of a glass or measuring cup for even compression.
Chocolate Technique: Don't overheat the chocolate or it will seize and become grainy. Stir frequently and remove from heat while a few chips remain, letting residual heat finish melting them.
Marshmallow Mastery: For the best texture, don't over-toast the marshmallows - they should be golden and slightly puffed, not completely melted or burnt.
Storage Solutions: Store bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week. They can also be frozen for up to 2 months.
Customization Options: Try dark chocolate chips, add peanut butter chips to the chocolate layer, or use honey graham crackers for extra sweetness.
Cutting Cleanly: For professional-looking bars, chill them completely before cutting and use a sharp knife dipped in hot water and wiped dry between each cut.

For the Graham Cracker Crust:

2 1/2 cups graham cracker crumbs, finely crushed
03
1/2 cup unsalted butter, melted
04
1/4 cup granulated sugar
05
1/4 teaspoon salt
06
For the Chocolate Layer:
07
2 cups semi-sweet chocolate chips
08
1 cup milk chocolate chips
09
1/4 cup heavy cream
10
For the Marshmallow Topping:
11
4 cups mini marshmallows
12
1/2 cup chocolate chips for garnish
13
For Special Equipment:
14
9x13 inch baking pan
15
Parchment paper
16
Kitchen torch or broiler

Instructions

01
Preheat oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper, leaving overhang on sides for easy removal.
02
In a large bowl, combine graham cracker crumbs, melted butter, sugar, and salt, mixing until texture resembles wet sand and holds together when pressed.
03
Press half of the graham cracker mixture firmly into the bottom of prepared pan, creating an even compact layer using the back of a measuring cup.
04
Bake the crust for 8 minutes until lightly golden and fragrant, then remove from oven and let cool for 5 minutes.
05
In a microwave-safe bowl, combine chocolate chips and heavy cream, microwaving in 30-second intervals, stirring between each, until completely smooth and glossy.
06
Pour the melted chocolate mixture evenly over the baked crust, spreading to edges with an offset spatula.
07
Scatter mini marshmallows evenly over the chocolate layer, pressing down gently to ensure they stick.
08
Crumble the remaining graham cracker mixture over the marshmallows, creating a textured top layer.
09
Sprinkle chocolate chips over the top for extra chocolate goodness.
10
Bake for 15-17 minutes until marshmallows are puffed and edges are golden brown.
11
For extra toasted marshmallow flavor, place under broiler for 1-2 minutes or use a kitchen torch to lightly toast the top (watch carefully to prevent burning).
12
Allow bars to cool completely in pan for at least 2 hours, then lift out using parchment paper overhang and cut into 16 squares with a sharp knife wiped clean between cuts.
